Multiple slides causing crash of app on iOS

Hi,
in my app I am getting about 4000 items from API in JSON. Each item is in <ion-slide>. Loaded 10 by 10 items when current index is items.length - 5. When I swipe multiple times, the app crash and I get error in xCode console:

Unable to acquire assertion for process with PID 0

Is there anyone who can tell me what this means?

Thanks a lot

Have you been able to isolate? I have had the same issue, memory leak seems the diagnosis, but tracking them down has been difficult…

Hi,
was able to load always only 30 items and I am changing them if current slide is length -5.
